Description

Technical Field

[0001] This invention relates to the field of pontoon bridge technology, and more particularly to a comb-shaped floating platform based on pile foundation clamp cantilever positioning. Background Technology

[0002] A slab-type high-pile wharf, also known as a slab-beam high-pile wharf, is a type of high-pile wharf. It is based on piles and consists of a slab foundation, longitudinal beams, transverse beams, and berthing components. The pile foundation is a slab-beam structure, which has a clear stress distribution, a large span, and allows for full utilization of pile force, while also being able to withstand continuous concentrated loads from gantry cranes, trains, and other heavy equipment.

[0003] In existing technologies, high-pile beam-slab wharves are commonly used on inland river shorelines and in harbor basins with breakwaters. They employ a permeable pile foundation structure, and their berths are typically located along the long side of the wharf, equipped with bollards for berthing large vessels. Due to insufficient turning area on the sides, berths are often not provided, making them unsuitable for large vessels. When smaller vessels such as yachts and transport boats need to berth in the same waters, the berths along the long side of the high-pile wharf cannot meet their berthing requirements. In such cases, a floating wharf is often constructed on a separate shoreline to address the berthing needs of smaller vessels. However, constructing a floating wharf on a separate shoreline is not only costly but also inconvenient for coordinating vessel berthing and management operations with the large high-pile beam-slab wharf. Furthermore, it fails to fully utilize the shoreline areas on both sides of the large high-pile beam-slab wharf, resulting in significant resource waste.

[0004] To address these issues, we propose a comb-shaped floating platform based on pile foundation clamp cantilever positioning. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems and proposes a comb-tooth structure floating platform based on pile foundation clamp cantilever positioning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A comb-shaped floating platform with cantilever positioning based on pile foundation clamps includes a wharf pile foundation. The wharf pile foundation is detachably connected to positioning piles via clamp plates. The positioning piles are movably connected to the floating platform via floating platform clamps. The floating platform is slidably connected to a footboard, which is slidably connected to the floating platform via a triggering mechanism. A limit mechanism is slidably connected to one end of the floating platform near the floating platform clamps. The limit mechanism is connected to the positioning piles via the triggering mechanism.

[0008] Adjacent clamp plates are fixedly connected by end bolts, and one group of clamp plates is fixedly connected to a T-shaped plate by stiffening ribs;

[0009] The floating platform clamp is provided with a groove, the positioning pile adopts an H-shaped steel structure, one end of the positioning pile is detachably connected to the T-shaped plate, and the other end of the positioning pile is slidably connected to the groove;

[0010] The floating platform clamp is detachably connected to the floating platform via a connecting plate. Both the floating platform clamp and the connecting plate are provided with through holes. The limiting mechanism, driven by the triggering mechanism, passes through the through holes to temporarily limit and lock the groove of the positioning pile.

[0011] The floating platform is equipped with a support bridge at the end away from the positioning pile, and the support bridge is fixedly connected to one end of the floating platform through the bridge brackets.

[0012] Optionally, the bottom of the pedal is provided with multiple sets of columns, and the floating platform is provided with multiple sets of sleeves. The columns are slidably connected to the sleeves through spring sets.

[0013] Optionally, the triggering mechanism includes a gear and a rack that mesh with each other, one end of the rack being fixedly connected to the pedal, and the other end of the rack being slidably connected to the floating platform via a gear sleeve;

[0014] The gear is coaxially fixedly connected to a screw rod, which, in conjunction with a slide rod, enables the sliding operation of the limiting mechanism.

[0015] Optionally, the limiting mechanism includes a soft magnetic plate, a movable magnetic block, and a limiting magnetic block. The soft magnetic plate is disposed inside the groove of the floating platform and is made of silicon-iron soft magnetic alloy.

[0016] One end of the movable magnetic block is slidably connected to the sliding plate and the floating platform, and the other end of the movable magnetic block is connected to the soft magnetic plate.

[0017] The limiting magnetic blocks are intermittently arranged on the side of the positioning pile near the groove. The magnetic field generated by the soft magnetic plate after the movable magnetic blocks are attached magnetically attracts and limits the limiting magnetic blocks.

[0018] Optionally, both the movable magnetic block and the limiting magnetic block are rectangular permanent magnets with their magnetic fields symmetrically distributed on both sides.

[0019] Optionally, the movable magnetic block is fixedly connected to a T-shaped rod, the T-shaped rod is movably connected to a sliding plate via a buffer spring, and the two ends of the sliding plate are slidably connected to the floating platform via screws and slide rods, respectively.

[0020] Optionally, the positioning pile is provided with multiple sets of sliding grooves, one end of the limiting magnetic block is slidably connected to the sliding groove through a return spring, the soft magnetic plate is provided with multiple sets of limiting grooves, and the other end of the limiting magnetic block is connected to the limiting groove through a wing plate.

[0021] The present invention has the following advantages:

[0022] This invention aims to save costs and maximize the utilization of the shoreline of a slab-beam high-pile wharf. When a large wharf requires the berthing of small vessels, a comb-tooth structure floating platform is developed using the pile foundations on the two short sides of the large high-pile slab-beam wharf, cantilevered and positioned. This comb-tooth structure floating platform, based on pile foundation clamps for cantilever positioning, can be used to meet the berthing needs of small vessels at the wharf, eliminating the need to construct a separate floating wharf. It efficiently utilizes the existing pile foundations on both sides of the high-pile wharf, saves construction costs, and is convenient and efficient to use. It can serve as an auxiliary facility for large high-pile wharves.

[0023] This invention maximizes the use of buoyancy in water, allowing the floating platform to operate while unattended. It prevents the platform from being submerged in high water or supported solely by buoy clamps in low water conditions. Temporary locking mechanisms are in place when personnel are present, preventing instability caused by movement or lingering on the platform. Furthermore, it effectively prevents accidental locking due to frequent high waves or other abnormal conditions that could damage the platform, thus significantly improving the platform's lifespan and performance.

[0024] This invention employs a trigger-type locking structure, which allows the rack and pinion fixedly connected to the pedal to rotate during the short-term stay of personnel on the pedal. The gear, through the coaxial fixed connection of the screw and slide bar, drives the slide plate to move horizontally. The slide plate, through the buffer spring, causes the movable magnetic block to gradually approach and adhere to one end of the soft magnetic plate. At this time, the soft magnetic plate is magnetized. When the soft magnetic plate is magnetized, it magnetically attracts and limits the limiting magnetic block, thus realizing the temporary locking of the floating platform.

[0025] The key feature of this invention is that when personnel frequently step on or remain on the floating platform, triggering a mechanism that causes the limiting magnetic block to adhere to one side of the soft magnetic plate, the soft magnetic plate, made of silicon-iron soft magnetic alloy, undergoes magnetic domain rearrangement due to the magnetic field, resulting in magnetization over a certain period. As the soft magnetic plate gradually magnetizes, it magnetically attracts the limiting magnetic block within the positioning column, temporarily locking the positioning column. This ensures that the floating platform only locks during periods of frequent personnel movement or lingering, preventing accidental locking due to conditions such as waves (frequent high waves can trigger the mechanism, causing wear and breakage of the limiting mechanism; therefore, the floating platform needs sufficient floating space). When personnel move away from the floating platform, the movable magnetic block moves away from the soft magnetic plate under the action of the triggering mechanism. After the soft magnetic plate demagnetizes over a certain period, the limiting magnetic block retracts under the action of the return spring, restoring the floating platform and positioning column to their floating state.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figure 1-5 The floating platform 5, based on the cantilever positioning of the pile foundation clamp, includes the wharf pile foundation 1. It should be noted that when small vessels need to berth in the waters of the large high-pile beam-slab wharf, the berths along the long side cannot meet the berthing requirements of the small vessels. Therefore, the pile foundations on both sides of the high-pile wharf are selected as the basis for building the floating platform 5 that can accommodate small vessels. The floating platform 5 is connected to the high-pile beam-slab wharf by a trestle bridge, so as to save construction costs, make efficient use of the shoreline, and maximize the use of resources.

[0034] Reference Figure 1 and Figure 2The wharf pile foundation 1 is detachably connected to positioning piles 3 via clamp plates 2. It is important to note that the clamp plates for the first-layer pile foundation are positioned 1m above the highest water level to prevent corrosion of the components by river or seawater and to avoid obstructing the floating platform 5 as it rises with the water level. A new pile foundation clamp is installed every 2m upwards from the first-layer clamp plate to ensure the secure and stable support of the cantilevered components. Clamp plates 2 consist of two Ω-shaped steel components with an inner diameter consistent with the outer diameter of the pile foundation, ensuring a tight connection between clamp plates 2 and the side pile foundations. The two ends of clamp plates 2 are butt-jointed and secured with bolts at the ends.

[0035] One set of clamping plates 2 is fixedly connected to T-shaped plates 22 via stiffening ribs 21. It should be noted that the clamping plates 2 are symmetrically welded with T-shaped plates 22, serving as the connecting device for the external cantilever of the clamping plates. At the same time, three pairs of pile foundation clamping stiffening ribs 21 are evenly spaced and welded to both sides of the T-shaped plates 22 from bottom to top, using full welding to ensure proper reinforcement, thereby bearing the shear force and bending moment received by the T-shaped plates 22 and enhancing the service life of the device.

[0036] The specific connection method between the clamp and the positioning pile 3: The clamp cantilever positioning device uses H-beam positioning piles 3 as cantilever positioning piles 3. One flange of the H-beam positioning pile 3 is bolted to the T-shaped plate 22. The web of the H-beam positioning pile 3 is aligned with the axis of symmetry of the T-shaped plate 22. With the web as the center, symmetrical holes are made on the flange near the T-shaped plate 22 in a "2*3" arrangement. At the same time, corresponding holes are made on the T-shaped plate 22. The positioning pile 3 is fixed with bolts through the holes in the H-beam positioning pile 3 and the T-shaped plate 22 to connect the H-beam positioning pile 3 and the T-shaped plate 22. When bolting the H-beam positioning pile 3 and the T-shaped plate 22, shims are placed to eliminate the loose connection caused by unevenness of the flange surfaces of the H-beam positioning pile 3 and the T-shaped plate 22.

[0037] The positioning pile 3 is movably connected to the floating platform 5 via the floating platform clamp 4. It is important to note that the floating platform clamp 4 has a groove, and the other end of the positioning pile 3 is slidably connected to this groove. Specifically, the floating platform clamp 4 connects the clamp cantilever positioning device to the floating platform 5, using a wear-resistant rubber sheet as a buffer to ensure that the floating platform 5 can move up and down along the positioning pile 3 as the water level rises and falls, while simultaneously preventing structural damage caused by continuous collisions between the floating platform 5 clamp and the H-shaped positioning pile 3 under dynamic water conditions.

[0038] More specifically, the wear-resistant rubber sheet is formed by stacking several sheets to create a buffer device. The wear-resistant rubber sheet wraps around the outer flange of the H-shaped positioning pile 3 on one side, with a distance of 5mm between the rubber sheet and the outer flange and web of the positioning pile 3. This ensures the buffer device has sufficient space to move up and down along the positioning pile 3 as the water level rises and falls. The thickness of the wear-resistant rubber sheet on one side of the positioning pile 3 is set to half the length of the H-shaped steel web. A rubber sheet pad is used to fix the wear-resistant rubber sheet to one side of the H-shaped steel positioning pile 3, ensuring the coverage area of ​​the wear-resistant rubber sheet around the H-shaped steel positioning pile 3.

[0039] The floating platform clamp 4 is detachably connected to the floating platform 5 via the connecting plate 41. It should be noted that the floating platform clamp 4 is detachably connected to the floating platform 5 via bolt holes pre-drilled in the stiffening rib plate 21 of the connecting plate 41. The distance between the outer flange of the positioning pile 3 and the rubber sheet limiting plate is set to half the length of the H-beam web, reserving installation space for the wear-resistant rubber sheet. The wear-resistant rubber sheet is close to the rubber sheet limiting plate on one side of the clamp on the floating platform 5. The fixing bolts of the positioning pile 3 pass sequentially through the rubber sheet pad, the wear-resistant rubber sheet, and the rubber sheet limiting plate, and are fixed to the connecting plate 41. By tightening the bolts on both sides of the rubber sheet pad and the rubber sheet limiting plate, several wear-resistant rubber sheets are compressed to form a buffer device.

[0040] Reference Figure 1 The floating platform 5 is equipped with a pontoon bridge 9 at the end furthest from the positioning pile 3. The pontoon bridge 9 is fixedly connected to one end of the floating platform 5 via pontoon bridge corner braces. It should be noted that both the floating platform 5 and the pontoon bridge 9 use hollow thin-walled high-performance concrete pontoons with foam floats embedded in the hollow space. Two pontoon bridge corner braces are added at the connection angle between the pontoon bridge 9 and the floating platform 5 to reinforce the connection node. The pontoon bridge 9 is installed on one half of the floating platform 5, and the other half is directly used as a berth, which can meet the berthing needs of vessels of different sizes.

[0041] Reference Figure 2 and Figure 3 The floating platform 5 is slidably connected to a footboard 6. It should be noted that the bottom of the footboard 6 is equipped with multiple sets of uprights 61, and the floating platform 5 is equipped with multiple sets of sleeves 53. The uprights 61 are slidably connected to the sleeves 53 through a spring assembly 62. When a person walks on the floating platform 5, the footboard 6 will slide downwards to a certain extent. When the person leaves the footboard 6, the footboard 6 will return to its original position under the action of the spring assembly 62. The gap between the footboard 6 and the floating platform 5 is small. The groove of the floating platform 5 for the footboard 6 to slide downwards has a drainage design. The footboard 6 only slides down to a certain extent and does not affect the normal movement of people.

[0042] Reference Figure 2 and Figure 3The pedal 6 is slidably connected to the floating platform 5 via the triggering mechanism 7. It should be noted that the triggering mechanism 7 includes a gear 71 and a rack 72 that mesh with each other. One end of the rack 72 is fixedly connected to the pedal 6, and the other end of the rack 72 is slidably connected to the floating platform 5 via a gear sleeve 73. Among them, the gear 71 is coaxially fixedly connected to a screw 74. Both ends of the screw 74 are rotatably connected to the floating platform 5 via bearings. The screw 74 cooperates with the slide rod 75 to realize the sliding operation of the limiting mechanism 8.

[0043] The floating platform 5 is slidably connected to a limiting mechanism 8 at one end near the floating platform clamp 4. The limiting mechanism 8 is connected to the positioning pile 3 through a triggering mechanism 7. The floating platform clamp 4 and the connecting plate 41 are both provided with through holes 52. Under the drive of the triggering mechanism 7, the limiting mechanism 8 passes through the through holes 52 to temporarily limit and lock the groove of the positioning pile 3.

[0044] Furthermore, referring to Figure 4 and Figure 5 The limiting mechanism 8 includes a soft magnetic plate 81, a movable magnetic block 82, and a limiting magnetic block 83. The soft magnetic plate 81 is disposed inside the groove of the floating platform 5 and is made of silicon-iron soft magnetic alloy. The limiting magnetic block 83 is intermittently disposed on the side of the positioning post 3 near the groove. The magnetic field generated by the soft magnetic plate 81 after the movable magnetic block 82 is attached magnetically attracts and limits the limiting magnetic block 83. It is worth mentioning that both the movable magnetic block 82 and the limiting magnetic block 83 are rectangular permanent magnets with their magnetic fields symmetrically distributed on both sides. When the limiting magnetic block 83 is attached to one side of the soft magnetic plate 81, the soft magnetic plate 81, made of silicon-iron soft magnetic alloy, will undergo magnetic domain rearrangement due to the magnetic field, resulting in magnetization within a certain period of time. As the soft magnetic plate gradually magnetizes, it will attract the limiting magnetic block 83 inside the positioning post, thus achieving temporary limiting of the positioning post.

[0045] Specifically, one end of the movable magnetic block 82 is slidably connected to the floating platform 5 via the slide plate 84, and the other end of the movable magnetic block 82 is connected to the soft magnetic plate 81. The movable magnetic block 82 is fixedly connected to a T-shaped rod 821. The slide plate 84 has a rectangular hole, and the T-shaped rod 821 is movably connected to the slide plate 84 via a buffer spring 822, ensuring that the movable magnetic block 82 does not shift during movement. Both ends of the slide plate 84 are slidably connected to the floating platform 5 via a screw 74 and a sliding rod 75, respectively. When personnel walk on the pedal 6, the pedal 6 slides up and down to a certain extent within the floating platform 5. At this time, the rack 72 drives the screw 74 to rotate via the gear 71. The screw 74, in conjunction with the sliding rod 75, causes the slide plate 84 to shift until the movable magnetic block 82 and the soft magnetic plate 81 gradually come into contact. During this process, the buffer spring 822 prevents rigid contact between the movable magnetic block 82 and the soft magnetic plate 81, while ensuring a tight fit between them.

[0046] More specifically, the positioning post 3 is provided with multiple sets of sliding grooves 31. One end of the limiting magnetic block 83 is slidably connected to the sliding groove 31 via a return spring 831. The soft magnetic plate 81 is provided with multiple sets of limiting grooves 811. The other end of the limiting magnetic block 83 is connected to the limiting groove 811 via a wing plate 832. It should be noted that the end of the positioning post near the groove is provided with multiple sets of strip-shaped openings. Under the limitation of the wing plate 832, the limiting magnetic block 83 is retracted and ejected by the return spring 831 and the positioning post. When the soft magnetic plate... After the movable magnetic block 82 is attached and magnetized, the limiting magnetic block 83 and the soft magnetic plate 81 are magnetically attracted to each other, which limits the positioning column and the soft magnetic plate 81. This prevents the floating platform 5 from floating during personnel movement, allowing the floating platform 5 to utilize the buoyancy of the water area to the maximum extent. This also prevents the floating platform 5 from being submerged when the water level is too high or from being supported by the floating platform clamp 4 when the water level is too low, effectively improving the service life of the floating platform 5.

[0047] The operating principle of the present invention is now described as follows:

[0048] When no one is moving around, the floating platform 5 floats on the outside of the pile foundation using its own buoyancy. This allows the floating platform 5 to utilize the buoyancy of the water area to the maximum extent, preventing it from being submerged when the water level is too high or supported by the floating platform clamps 4 when the water level is too low, thus effectively improving the service life of the floating platform 5.

[0049] When people walk on the floating platform 5 or when people walk under it after the ship has docked, the platform 6 slides down slightly the moment a person steps on it. At this time, the rack 72 fixedly connected to the platform 6 drives the meshing gear 71 to rotate. The gear 71 drives the sliding plate 84 to move horizontally through the screw 74 and slide bar 75 fixedly connected to the same axis. This causes the movable magnetic block 82 to gradually move closer to one end of the soft magnetic plate 81 until the movable magnetic block 82 and the soft magnetic plate 81 are in contact and magnetized. The soft magnetic plate 81, made of silicon iron soft magnetic alloy, will be affected by the magnetic field. The action of the soft magnet causes the magnetic domains to rearrange, resulting in magnetization within a certain period of time. As the soft magnet gradually magnetizes, it attracts the limiting magnetic block 83 in the positioning column, allowing the limiting magnetic block 83 to be inserted into the limiting groove 811 of the soft magnetic plate 81 through the magnetic attraction between it and the soft magnetic plate 81. At this time, the limiting magnetic block 83 creates a limiting effect between the positioning column and the soft magnetic plate 81 through the wing plate 832, thereby achieving temporary limiting between the floating platform 5 and the positioning column, preventing the floating platform 5 from floating during personnel movement.

[0050] After personnel exit the footplate 6 of the floating platform 5, the movable magnetic block 82 moves away from the soft magnetic plate 81 under the reset of the triggering mechanism 7. After a certain period of time, the soft magnetic plate 81 loses its magnetism, causing the limiting magnetic block 83 to be reset and retracted into the positioning column under the action of the reset spring 831, so that the floating platform 5 and the positioning column return to their floating state.

[0051] The above description is only a preferred embodiment of the present invention. It is impossible to exhaustively describe all embodiments here. However, the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the protection scope of the present invention.
